Description

refrigerator [Reference to related applications]

The present application is based on and claims the benefit of priority to Japanese Patent Application No. 2012-210381, filed on-

The embodiment described herein is generally related to a refrigerator.

In order to improve the heat insulating performance, the inside of the outer wall portion, the top portion, the bottom portion, and the like of the refrigerator are filled with a heat insulating material for heat insulation. Further, the inside of the door on the front side of the refrigerator is filled with a heat insulating material to constitute a heat insulating door having improved heat insulating performance.

In the conventional heat insulating door, the space between the front plate and the rear plate constituting the door is filled with a foaming urethane as a heat insulating material. In the case where an insulated door using such a foamed urethane is used for a door of a refrigerator, in order to open the door, for example, a bar type handle or a handle portion must be provided at the door. The column type handle is attached to the front surface of the door by screws or the like. On the other hand, the handle portion is formed by, for example, recessing the front plate constituting the door toward the inside of the refrigerator, and projecting the upper portion of the recessed portion toward the front as eaves and bending downward. By Put your finger on the handle and open the door to the front side.

When such a handle portion is provided in the heat insulating door, the front plate of the door is recessed, so that the thickness of the heat insulating door of the recessed portion is reduced. In the case of using a foamed urethane, since the thickness of the door is made thick, even if such a recess is present, the heat insulating performance of the heat insulating door is not greatly impaired.

In recent years, a vacuum heat insulating material which is thin but has improved heat insulating properties has been used instead of the foaming urethane. By adhering the vacuum insulation material to the back side of the front panel of the door, the insulation performance of the door is improved and the door is made thinner, and the internal capacity of the refrigerator compartment is increased.

In order to use the vacuum heat insulating material as the heat insulating material of the door and to provide the handle portion to the door as described above, it is necessary to form the concave portion on the front plate of the door.

Due to the presence of such a recess, the vacuum insulation material cannot be adhered to the front panel of the door. Therefore, there is a problem that a vacuum heat insulating material cannot be used to obtain a door having an improved heat insulating performance and a thinner thickness.

The present invention provides a refrigerator which uses a vacuum heat insulating material as a heat insulating material for a door to improve heat insulating performance and to increase internal capacity.

The refrigerator of the embodiment includes a vacuum heat insulating material, a concave portion constituting a handle portion of the door, and a shaped heat insulating material. The vacuum heat insulating material is disposed to abut against the back side of the front panel constituting the door. The recess is provided at a position different from a position at which the vacuum heat insulating material is disposed on the front panel. The molded heat insulating material is disposed on the back side of a portion of the front plate corresponding to the position of the concave portion.
